The use of a selected aminoalkyl glusoaminide 4-phosphate (AGP) CRX-547 to induce a TRIF biased response in a human system, which results in reduced levels of MyD88-dependent cytokines relative to the MyD88-dependent cytokines induced by its diastereomer AGP CRX-527.本発明は、TLR4受容体複合体を介してTRIFバイアスシグナルを誘発するための合成リピッドA模倣物、特にAPG化合物CRX547の使用に関する。
